At present, the material that generally adopts of the heat exchanger tube wall of tube type indirect evaporative cooler is that metal aluminum foil is made.Because the heat exchanger tube wall that metal aluminum foil is processed is a kind of non-hydrophilic surface; So moisture film can not be evenly distributed on the heat exchanger tube wall in the tube type indirect evaporative cooler running; Heat exchanger is in operation under the dry cooling condition at the part tube outer surface; Outer moisture film and the auxiliary air of heat exchanger tube can not carry out sufficient caloic exchange in this case, thereby caused having reduced to a certain extent the heat exchange efficiency of tube type indirect evaporative cooler, the energy consumption when having increased operation.For heat and mass transfer enhancement, improve heat exchange efficiency, just need improve the hydrophily of the heat exchanger tube wall of tube type indirect evaporative cooler.
Summary of the invention
The purpose of the utility model provides the tube type indirect evaporative cooler that a kind of heat exchanger tube coats the hydrophily plastic sheeting outward; The heat exchanger tube wall hydrophilicity that has solved common tube type indirect evaporative cooler is poor, the problem that heat exchange efficiency is low and unit operation energy consumption is high.
The technical scheme that the utility model adopts is; A kind of heat exchanger tube coats the tubular indirect evaporative cooler of hydrophily plastic sheeting outward; Include the cabinet of tube type indirect evaporative cooler itself, cabinet inside is provided with water spraying tray, and the bottom of water spraying tray is provided with the many heat exchanger tubes that are arranged in parallel; Heat exchanger tube is coated with the hydrophily plastic sheeting through Corona discharge Treatment; The bottom of tube type indirect evaporative cooler cabinet one side is connected with an end of water inlet pipe, and the other end of water inlet pipe is connected with water spraying tray, and water inlet pipe is provided with water circulating pump.
The characteristics of the utility model also are,
Heat exchanger tube wherein is the smooth pipe of metal aluminum foil material, smooth elliptical tube or smooth flat tube.
The beneficial effect of the utility model is:
(1) plastic sheeting being carried out surface hydrophilicity handles; Process pipe box according to the size of heat exchanger tube then; Pipe box is enclosed within outside the tube type indirect evaporative cooler heat exchanger tube; Improved the hydrophily on tube type indirect evaporative cooler heat exchanger tube surface, made moisture film being more evenly distributed of heat exchanger tube wall, more frivolous, the water consumption of heat exchanger tube wall per surface area reduces; Thereby saved the power of indirect evaporation cooler water consumption and water circulating pump, realized that indirect evaporation cooler is energy-conservation, the effect of water saving;
(2) owing to the very thin thickness of plastic sheeting, thermal resistance is very little, therefore can improve the indirect evaporation cooler exchange performance, has not only improved the latent heat exchange of auxiliary air side, has also improved the sensible heat exchange of primary air side simultaneously;
(3) because plastic sheeting self has series of advantages such as corrosion-resistant, light weight, low cost of manufacture and long service life, make it can be used for the clad material of tube type indirect evaporative cooler heat exchanger tube on a large scale;
(4) because the plastic sheeting that is coated on the heat exchanger tube outer wall can be exchanged heat pipe plays a good protection, alleviated the erosion of incrustation scale, improved the heat exchange efficiency of primary air side greatly the tube type indirect evaporative cooler heat exchanger tube.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
The structure of the utility model tube type indirect evaporative cooler; As shown in Figure 1; Include the cabinet of tube type indirect evaporative cooler itself, cabinet inside is provided with water spraying tray 1, and the bottom of water spraying tray 1 is provided with the many heat exchanger tubes that are arranged in parallel 2; Heat exchanger tube 2 is coated with the hydrophily plastic sheeting 4 through Corona discharge Treatment, and the structure of heat exchanger tube 2 is as shown in Figure 2.The bottom of tube type indirect evaporative cooler cabinet one side is connected with an end of water inlet pipe 5, and the other end of water inlet pipe 5 is connected with water spraying tray 1, and water inlet pipe 5 is provided with water circulating pump 3.
Wherein the tubing of heat exchanger tube 2 is for coating the metal aluminum foil material of hydrophily plastic sheeting, tubularly can be smooth pipe, smooth elliptical tube or smooth flat tube.Directly do not contact with auxiliary air at the inner primary air of Air conditioner box; Primary air passes through in heat exchanger tube 2; Make the heat exchanger tube 2 outer moisture films that form through water circulating pump 3 spray recirculated waters; The outer moisture film of auxiliary air and heat exchanger tube carries out the wet exchange of heat, and the wall of primary air through heat exchanger tube 2, moisture film are realized the purpose of lowering the temperature with the heat transferred auxiliary air.
Through Corona discharge Treatment is carried out on the plastic sheeting surface, make the frosting activation, can improve hydrophily, for plastic sheeting,, must carry out corona treatment to increase its surface tension because its initial surface tension force is less.Plastic sheeting is carried out corona treatment can produce following effect.The first, remove the material that is adsorbed on film surface; The second, promote the contact between the atom, promote wettability; The 3rd, the surface tension of raising plastic sheeting is regulated polarity; The 4th, destroy the part chemical bond on plastic sheeting surface, the functional group that generation can chemically reactive regulates the surface polarity of plastic sheeting etc.Above-mentioned processing, can directly increase film the surface can, strengthen the mobility of polar group.
